LEATHER-FACED FABRIC FOR USE IN BOO'KBINDING, 800.

SPECIFICATION forming part of Letters Patent No. 251,065, dated December20, 1881. Application filed July 27, 1881. (No specimens.)

T all whom it may concern:

Be it known that 1, WILLIAM PYLE, a citizen of the United States,residing atWilmington,in the county of New Castle and State of Delaware,have invented a new and useful Fabric for use in Binding Books and otherpurposes, of which the following is a specification.

The nature of this invention will fullyappear "from the followingdescription.

It is well known to leather manufacturers, particularly tomanufacturersof pat ent leather, that the outer or grain side ofhide-leather has been shaved off by means of the curriers knife; butthat within a few years past the splitting or skiving machines have beenso improved that this outer grain is accurately split off in acontinuous thin sheet, and this is known in the trade as buffing.Itpossesses, however, comparatively little strength, and has but limiteduse or demand in bookbinding, or ftr imilar purposes.

The object of my invention is to extend the use of such buffingbycombining and manipulating the same as hereinafter described. To thisend I take the piece or sheet of thin butt ing as it comes from thesplitting-machine and cement to the out side thereof a sheet of cottoncloth by means ot'a flexible adhesivepastesuch,forexample,asindia-rubber cement. Any other cheap materialsufficiently pliable and otherwise adapted for the purpose in view maybe employed in lieu of cotton cloth, and it may be ofany desiredqualityor thickness. This, as well as the cement, to some extent,lendsstrength and body to the buffing. Thecement having been applied betweenthe contiguous surfaces of cloth and bailing, I compress the unitedsheets between rollers,or other\vise,so as to cause as close and perfectadhesion as possible. I prefer to use india-rubbercement,

for the reason that, while it is soft and pliable, it is at the sametime water-proof, thus preventing the separation of [he butting from thecloth, which would otherwise be apt to occur to a greater or less extentwhen the fabric is applied with glue or paste containing water to theback of the book or other article in process of binding.

It is usually desirable to produce a grained or pebbled appearance ofthebuffing, and it is also sometimes important to have as large orprominent a pebbling as maybe. This I attain in the usual Way, or byrollingthe fabric upon itself after the sheetshave been firmly joinedtogether and the cementhas set; t'oril'the pebblingwere done before, therolling or other pressure to which the stufi'is subjected in order tocau e the sheets the better to adheretogether would more or less smoothout and injure the appearance of the pebbling. Besides, it is obvious tothose skilled in the art that aniuch morepronounced orlargergrainingresults(becauseol'the greater body or thickness of the combined fabricas compared with the butting) than would be the case if the butting beseparately pebbled by rolling it upon itself. The material being thusprepared, it is supplied to the trade and the eonsumerin sheets ofsuitable size, readyto be cut up and applied as an outer covering inbookbinding or other purpose by pasting it, on in the usual way. Thefabric has the quality and appearance of good leather, and is muci moreeconomical.

Having thus desrribed my invention, I claim- 1. As a new article ofiminufacture, a fabric constructed of a sheet of batting and a sheet ofcotton cloth, or its equivalent, cemented together, substantially as andfor the purpose set forth.

2. As a new article of manufacture, a fabric composed of leather buffingand cloth, or its equivalent, united by atlexible\vater-proofcement,substantially as and for the purpose described.

3. As a new and improved article of manufacture, the pebbled fabric madeas and for the purpose llGIQlllbtfuIU specified.

4. Thedescribed method of mak ng fabrics for use in binding books, whichconsists in ('cmenting together a sheet of leather butting and a sheetof cotton cloth, or its equivalent, and subsequently pebbling thebutting, as and tor the purpose set forth.

XVILLIAM PYLE.
